In other words, uncertainty has increased,” Novak said after meeting the Saudi minister.Novak added that the OPEC+ was able to offset global changes in the energy sector, nonetheless. “Estimates made just a few years ago now need to be fundamentally revised,” Novak said.Russian oil production has fallen since the start of the year, Novak said, blaming the decline on unplanned maintenance at refineries. This was the first explicit acknowledgement by a Russian official of lower output, according to the Reuters news agency.Novak did not state the reason for the refinery maintenance, but Ukraine has intensified attacks on Russian refineries in recent months.The closure of the Strait of Hormuz due to the US-Israel war on Iran and subsequent forced cuts in oil exports by the Gulf OPEC members and former member, the UAE, have rendered their agreements to raise oil output quotas largely theoretical.Reuters reported that Saudi Arabia, Russia, and five other OPEC+ countries would likely agree to a further hike in their output target for July when they meet on Sunday, quoting unnamed sources.
